Cats in a cage: Novel hybrid nanocages for faster catalysis

A novel hybrid ferritin nanocage with histidine residues shows 1.5 times higher metal ion uptake and improved catalytic efficiency for alcohol production, according to researchers from Tokyo Tech in a new study. Their findings ...

Engineered protein crystals make cells magnetic

If scientists could give living cells magnetic properties, they could perhaps manipulate cellular activities with external magnetic fields. But previous attempts to magnetize cells by producing iron-containing proteins inside ...

Nanoscale magnetic imaging of ferritin in a single cell

In life sciences, the ability to measure the distribution of biomolecules inside a cell in situ is an important investigative goal. Among a variety of techniques, scientists have used magnetic imaging (MI) based on the nitrogen ...

Marine bacterium sheds light on control of toxic metals

An ocean-dwelling bacterium has provided fresh insights into how cells protect themselves from the toxic effects of metal ions such as iron and copper, in research led by the University of East Anglia (UEA).

Bioluminescent worm found to have iron superpowers

Researchers at Scripps Institution of Oceanography at the University of California San Diego have made a discovery with potential human health impacts in a parchment tubeworm, the marine invertebrate Chaetopterus sp., that ...

New Alzheimer's research method uses muons

Alzheimer's disease is the most common form of dementia. This makes fundamental research on the precise cause of the illness of vital importance. One of the possible suspects is a certain protein filled with iron. Leiden ...
